In the previous blog post, I wrote about our problem with JVM CodeCache. This cache is used for saving compiled machine code and if your Java application generates new code on the fly, it will eventually fill.
As a Java developer, you don't need to know internal details of JVM most of the times. The virtual machine is not a trivial piece of technology and learning internal details can be scary. But there are times, when you find something interesting in the logs, which seems to be important. Like the message: CodeCache is full. The compiler has been disabled. Try increasing the code cache size using -XX:ReservedCodeCacheSize=
For our internal purposes and also for several of our customers we either introduced or used Atlassian JIRA. We see this tool as an amazing platform which can serve purposes of software development teams but also to entirely non-IT related projects. One of the small problems that we faced was rendering a screen of an issue with many subtasks. Simply to get an overview of all the subtasks which belong to a common parent means lots of clicking to the parent and then another subtask.
I use Google a lot in my job. Not only to search things I don't know, but also things I should know very well. For a long time, I didn't feel good about it. Until, I read this stream of confessions from skilled senior developers on the Twitter. As a developer interested in graphics, I should know that using references isn't bad. Graphics use references all the time and they don't feel bad about it. In fact, it is advised to use them. The final result is what matters.
My question targets not only desktop software but also mobile apps, web applications, and websites. Seems like software is getting worse and it won't be better. And I just have to start my rumble with the worst - mobile apps.
Sooner or later it is unevitable to secure your database. At least in my opinion... It was the first time I was securing a MongoDB instance and when I was looking for some information I came across this blog post. At first, if you want to set up username&password authentication for your MongoDB instance, you will find the article really helpful. Secondly, you can take much more from the post...specifically almost 600TB of data from all around the world (if you wish of course).
I just recently saw someone joking about Scrum on the Twitter. He wasn't very fond of Scrum because by his own words, "What kind of methodology is it, when it needs a single dedicated person to enforce it?" We are talking about Scrum Master role here. I'm having many problems with this statement.
I was wondering since I am in a business and since I am in an IT, why these two sectors were seen separately for such a long time. It seems last few years people started realising they can work together. Nowadays, they are many companies based simply on the digital products, look at Airbnb, Uber, Google, Spotify.. without the technology and some algorithms plus great programmers they are nothing.
Let's face the Continuous Integration the development practice that requires developers to integrate code into a shared repository at least once a day per developer. Each check-in is then verified by an automated build, allowing teams to detect problems early.
